|

| 37 | When data is input into Data-RAM by the DataGenerator, the data is fed in as words of 64bit.
|
|---|
| 38 |
|
|---|
| 39 | Each Event constists of an EventHeader, the so called ChannelData, and a small EventFooter.
|
|---|
| 40 | Figure (\ref{64bitRAM}) shows how the data is stored as 64bit words in the DataRAM.
|
|---|
| 41 | Assume the Event Start-Address beeing {\tt 0x2000} and each package of ChannelData consists 100 samples.

| 91 | During DRS readout and data digitzation, the Trigger ID is coming in through RS485 interface from FTM board.
|

| 92 | The Trigger ID reciption takes about $40 {\mu}$s. Therefor the 2 words containing Trigger information in the EventHeader are
|
|---|
| 93 | left empty in the first place. The digitazed analog data is read in as quickly as possible. Only after finishing the Readout,
|
|---|
| 94 | the Trigger ID is filled into the EventHeader.
|
|---|
| 95 | Then the EventFooter is added and the Readout is finished.

|

| 100 | After an Event is stored in data RAM, is is ready to be read out by {\tt w5300 modul.vhd}.
|
|---|
| 101 | Since the FIFOs of FADs W5300 ethernet controller are of 16bit width, data is read out of the dataRAM
|
|---|
| 102 | as 16bit words. Empty 16bit words are left out.
|

| 166 | As one can see, the way of reading out of the RAM changes, from header to data section and again when data section ends.
|
|---|
| 167 | When reading the header, the addresses are increased by 1 usually and only jumps, when empty words show up in the RAM.
|
|---|
| 168 | One can picture it as if reading the words in each line from right to left, sometimes jumping over zeroes.
|
|---|
| 169 | When reading out the data sections, the words are read out as columns, i.e. addresses are incremented by 4 usually. One column is read until the data of a channel is completely read out, then either the next DRS chip is read out, which means to decrease the address or, if one group of channels was finished, the next group starts, which means address is increased by 1 only.
|
|---|
| 170 | The footer consisting of the CRC-16 (when finally implemented) and the end package flag is again read out by reading each word from right to left.
